Question: passage: Bull sharks can thrive in both salt and fresh water and can travel far up rivers. They have been known to travel up the Mississippi River as far as Alton, Illinois, about 700 miles (1100 km) from the ocean. However, few freshwater human-shark interactions have been recorded. Larger-sized bull sharks are probably responsible for the majority of near-shore shark attacks, including many bites attributed to other species.
 question: are there any sharks in the mississippi river?

Answer: Yes


Question: passage: Article Five of the United States Constitution describes the process whereby the Constitution, the nation's frame of government, may be altered. Altering the Constitution consists of proposing an amendment or amendments and subsequent ratification. Amendments may be proposed either by the Congress with a two-thirds vote in both the House of Representatives and the Senate or by a convention of states called for by two-thirds of the state legislatures. To become part of the Constitution, an amendment must be ratified by either--as determined by Congress--the legislatures of three-quarters of the states or state ratifying conventions in three-quarters of the states. The vote of each state (to either ratify or reject a proposed amendment) carries equal weight, regardless of a state's population or length of time in the Union.
 question: can the articles of the constitution be amended?

Answer: Yes
